Abstract: A holder for a multiplicity of paper clips is arranged in an aligned stack disclosed herein having an elongated, hollow housing closed at a dispensing end with a stop defining a partial opening for passing the uppermost clip of the stack. The housing dispensing end includes an outwardly projecting bill or lip adapted to present the uppermost clip in a preparatory position for manual removal from the housing. A spring biasing mechanism is incorporated into the housing closing the end thereof opposite to its clip dispensing end which includes a guide rod projecting through aligned openings in the stack of clips and a slidable foot carrying the clip stack. An expansion spring is disposed on the rod between the foot and a base which is snap-locked with the housing to close the housing storage cavity.
